Cleanup overly complicated code.
2021-06-29 Ed Schonberg <schonberg@adacore.com>
* exp_aggr.adb (Convert_Aggr_In_Object_Decl): After expansion of
the aggregate, the expression can be removed from the
declaration, except if the object is class-wide, in which case
the aggregate provides the actual type. In other cases the
presence of the expression may lead to spurious freezing issue.
* exp_ch3.adb (Expand_N_Object_Declaration): If the expression
in the declaration is an aggregate with delayed expansion (as is
the case for objects of a limited type, or a subsequent address
specification) the aggregate must be resolved at this point.
This resolution must not include expansion, because the
expansion of the enclosing declaration will construct the
necessary aggregate expansion.

variant.

cases of function instances whose entity is
N_Defining_Identifier rather than N_Defining_Operator_Symbol.
(Can_Override_Operator): Function declaration moved to package

documentation: Repinfo is the package where these negative

* sem_ch13.ads, sem_ch13.adb (Check_Size): Do not set Esize and
RM_Size. This is unnecessary in the case of Size. For

types Node_Kind and Entity_Kind, which is not true.
